By using this app, you will be able to monitor and control the home appliances from any part of the world with ease. Combined with an Arduino and some off-the-shelf remote control sockets, it makes controlling AC appliances easy. You can add temperature sensors, and even control your TV - but we'll be keeping things basic today and extending the project in a later tutorial. You can sync entertainment devices with other gadgets like voice control tools and even exercise machines to create a more user-friendly and feature-rich experience.
It’s fairly easy to replicate and requires only a handful of components. Arduino community member Roboro built this project where he connected a stationary bike to an Arduino Nano, allowing him to control the streaming of Netflix on a PC. While we used a single relay in this example, you can easily expand your system by using a multi-channel relay module.
Step 10: Final Output
Stop the Heimcontrol app if it's running and install the Arduino bridge using the following command. I've used some reasonably cheap £20 sets from Maplin which come with 3 sockets, and opened up the remote control so I could interface directly with the 433 MHz chip inside. The installation process is quite laborious, and derived from the instructions here. Unfortunately, these were outdated or not designed for Raspian, so I've adjusted them heavily below. The codes below can mostly be pasted in blocks - you needn't paste one by one.
While this is usually best done using alogic level converter, we’re instead just using a simple voltage divider to convert the 5V signal into a 3.3V signal. This is because the Arduino is based on an ATmega328 microcontroller which defines a logic high as any level above 3V. 1) Connect the Arduino’s +5V and GND pins to the bus strips on the breadboard, as shown in the above circuit diagram. Make a table arrangement with 3 rows, and add a label to each row, for individual lights.
Home Automation using IoT Project Description:
If you have a Raspberry Pi and an Arduino, you can basically achieve the same thing at a fraction of the price, assuming you're willing to put in the time and the effort. You can follow any responses to this entry through the RSS 2.0 feed. Smart entertainment systems are easier to control and navigate. Smart tech makes it easier to change the volume, switch between systems, and get more out of your entertainment device’s features. Nodemcu is a versatile platform that can be used for a variety of home automation applications. With a little creativity, you can use it to create a system that is perfect for your home and your family.
Then, you can connect the ESP boards to actuators to actually control something and to sensors to monitor your house. In this Module, you’ll get started with Node-RED software on the Raspberry Pi. You’ll install Node-RED, learn some basic concepts, and create simple flows to control the Raspberry Pi GPIOs.
Steps :-
It is not mandatory to have all the recommended prerequisites to follow along as the eBook is step-by-step style. To program the ESP32 and ESP8266 boards, we’ll use Arduino IDE. This section provides additional information that might be useful like executing commands on the Raspberry Pi using Node-RED and a quick guide with Linux commands. If you don’t have a Raspberry Pi to follow along, you can create your system on the cloud.
2) Power the HC-05 module by connecting the 5V and GND pins to the bus strips on the breadboard. Finally, in the void loop, we check for commands from the Bluetooth serial and turn on and off the lights accordingly. BTserial object, you would have to mention the order of the Tx and Rx pins as connected in the Arduino.
Node-RED runs on the web browser and uses visual programming that allows you to connect code blocks, known as nodes, together to perform a task. With Node-RED you can spend more time making cool stuff, rather than spending countless hours writing code. Home automation is a term used to describe the process of automating certain tasks and devices around the home.
You can also purchase individual 433 MHz transmitters ready for use on eBay or from hobby electronics suppliers. All you need to is connect the VCC to 5 V on the Arduino, the GNDs, and a single control pin - remember which one you used. This last command will launch the Mongo server, and you'll need to open a new Terminal to continue with the other commands. I'm not entirely confident of this step, so if anyone can correct this in the comments on how to have mongod launching automatically on start up, it would be much appreciated.
Instead of using mechanical switches, you can now conveniently control all the devices in your home from your fingertips. In the void setup, we set up the serial monitor and virtual Bluetooth serial at 9600 baudrate. Next, we check what button was clicked in the horizontal component, and send the appropriate message to the HC-05 module. Next, make a function to auto-connect to the HC-05 Bluetooth module when the screen is initialized.
Here is a Simple DIY Home Automation System Code, you can copy the code and paste it in your Arduino IDE. But before that, you need to add Blynk Library to Arduino IDE. Finally, you can use nodemcu to create a home automation system that is completely customised to your needs. Maker.pro needs to review the security of your connection before proceeding. Here is a link for a small solid state relay package that is offered in 2,4, or 8 channels. 2) Next, it will list all the available devices in your vicinity. You can either upgrade to a higher current relay, or place multiple relays in parallel.
In order to that, you’ll need to download the Arduino Bluetooth Controller app on your Android device. When the relay is off, the COM terminal is connected to the NC terminal, which means if you connect the bulb to the NC terminal, it will turn ON even when the relay isn’t energized. The relay module we’re using can handle up to 10 amps of current at up to 240V AC. Once you have connected the HC-05 module to the Arduino, you can power the Arduino with a 12V DC supply or USB cable. This crude solution should never be used with a high-speed signal because the resistors form a low-pass RC filter with any parasitic capacitance on the connection.
You’ll also learn about Node-RED dashboard, a set of nodes to easily create a user interface. Node-RED is a powerful open-source tool for building Internet of Things applications with the goal of simplifying the programming component. You can build a complete home automation system without having to write a single line of code.

With his system you can monitor for water leaks, see if the garage door is open, check for new mail, watch for movement, sense for gas, and even see how the dog is doing. The system uses both an Arduino and a Raspberry Pi alongside a ton of various sensors to monitor the house. You can set up the system to send you alerts when something happens or just monitor everything from your phone. Blynk is a platform with iOS and Android apps that allows you to control your Arduino, Raspberry Pi, or ESP8266 from your mobile phone.
